COM 830

Onboard Microcontroller

The COM 830 is equipped with an ATMEL Atmega168 microcontroller. This onboard microcontroller plays 
an important role for most of the  BIOS features. It fully isolates some of the embedded features such as 
system monitoring or the I²C bus from the x86 core architecture, which results in higher embedded feature 
performance and more reliability, even when the x86 processor is in a low power mode.

Embedded BIOS

The COM 830 is equipped with  Embedded BIOS and has the following features:

ACPI Power Management

ACPI Battery Support

Supports Customer Specific CMOS Defaults

Multistage Watchdog

User Data Storage

Manufacturing Data and Board Information

OEM Splash Screen

Flat Panel Auto Detection

BIOS Setup Data Backup

Fast Mode I²C Bus
